[發明所欲解決之問題][Problems to be Solved by Invention]

然而，關於可折疊式保冷容器，於專利文獻1之態樣中存在如下問題，即，於折疊保冷容器時，必須卸除袋體內之各個面之絕熱材，從而未必能簡易地進行折疊，又，由於其構造會於各個面之絕熱材間出現間隙，故而保冷效果會大幅降低。However, with regard to the collapsible cold storage container, the aspect of Patent Document 1 has the following problems. When the cold storage container is folded, the heat insulating material on each surface of the bag body must be removed, so that it is not always possible to fold easily. , due to its structure, there will be gaps between the insulating materials on each surface, so the cooling effect will be greatly reduced.

又，關於保冷袋，於專利文獻2及3之任一者之態樣中，亦存在如下問題，即，由於其構造為即便使各個面之絕熱部密接，內部之冷氣亦會自其間隙漏出至絕熱材之外，故而難以確實地維持保冷效果。另一方面，於一體地成形各個面之絕熱部之情形時，儘管保冷效果有所改善，但仍存在如下問題，即，不僅耗費用以一體成形之成本或勞力，而且在卸除絕熱部時，需要始終將整體一體地卸除。Furthermore, with regard to the cold storage bag, in the aspect of any one of Patent Documents 2 and 3, there is a problem that even if the heat insulating portions of the respective surfaces are closely contacted, the cold air inside leaks out through the gaps. In addition to the heat insulating material, it is difficult to reliably maintain the cooling effect. On the other hand, in the case of integrally molding the heat insulating portions of the respective surfaces, although the cooling effect is improved, there is still a problem that not only the cost and labor for integral molding are consumed, but also the removal of the heat insulating portions is problematic. , it is necessary to always remove the whole as a whole.

本發明係鑒於上述情況而完成者，目的在於可容易地折疊保冷袋並且提昇保冷效果。此外，本發明之另一目的在於，不僅可更簡易且低成本地進行各個面之絕熱部之成形，而且藉由確實地減少冷氣自各個面之絕熱部間流出，提昇保冷效果。本發明之其他目的藉由參照本說明書之全文而明確。  [解決問題之技術手段]The present invention has been made in view of the above-mentioned circumstances, and an object of the present invention is to easily fold a cold storage bag and to improve the cooling effect.

The bottom surface of the bag body 23 is opened and closed by rotating around the hinge member, and the bottom surface is configured to be adjacent to the side portion of the outer surface of the bag body 23 when the cooling bag 1 is folded. In addition, the cover body 27 described below is similarly configured to be adjacent to the side portion of the outer surface of the bag body 23 when the cold storage bag 1 is folded. In addition, the bag body 23 is formed of a soft material so that it can be folded including the heat insulating portion.

由與袋本體23相同之材料形成之蓋體27經由以合成樹脂片構成之鉸鏈構件(未圖示)連結於收納口之一側(下述背面側側面35)，於蓋體27之周緣部設置有於將該蓋體27蓋住收納口時(利用蓋體27封閉收納口時)覆蓋袋本體23之上部外周之拉鏈部29，該拉鏈部29係沿著該外周延伸設置。此處，於蓋體27之內表面設置收容有絕熱材之絕熱部作為上表面絕熱部。再者，可考慮各種態樣來將絕熱材安裝於蓋體27，並不限定於特定態樣。A lid body 27 formed of the same material as the bag body 23 is connected to one side of the storage opening (rear side side 35 described later) via a hinge member (not shown) composed of a synthetic resin sheet, at the peripheral edge of the lid body 27 A zipper portion 29 is provided to cover the upper outer periphery of the bag body 23 when the lid 27 covers the storage opening (when the lid 27 closes the storage opening), and the zipper portion 29 extends along the outer periphery. Here, a heat insulating portion containing a heat insulating material is provided on the inner surface of the lid body 27 as an upper surface heat insulating portion. In addition, various aspects can be considered and the heat insulating material is attached to the cover body 27, and it is not limited to a specific aspect.

此處，該保冷袋1亦可具備一對之兩端部安裝於該袋本體23之手提式把手33。例如，如圖1、2所示，該手提式把手33安裝於袋本體23之正面側側面31及背面側側面35之上部外周，但並不限於此。又，於圖示之例中，該手提式把手33構成為一對U字形把手37、39。再者，該手提式把手33即兩個U字形把手37、39例如亦可於用手搬運保冷袋1時，中央部分可由縫合有魔鬼氈43、45之環狀之把手合攏抓手47收攏為一體。Here, the cold-insulation bag 1 may also include a pair of portable handles 33 whose both ends are mounted on the bag body 23 . For example, as shown in FIGS. 1 and 2 , the portable handle 33 is attached to the upper outer periphery of the front side side 31 and the back side side 35 of the bag body 23 , but it is not limited thereto. In addition, in the example shown in the figure, the portable handle 33 is configured as a pair of U-shaped handles 37 and 39 . Furthermore, the portable handle 33, that is, the two U-shaped handles 37 and 39, can also be used to carry the cold-insulation bag 1 by hand. one.

又，該保冷袋1亦可具備兩端部安裝於該袋本體23之肩帶(shoulder belt)53。於此情形時，例如，如圖1、2所示，該肩帶53可以如下方式形成，即，於袋本體23之左右側面49、51間，架設一條由織布或合成樹脂(成形品)、布帛、皮革等構成之薄帶狀之肩帶53，該肩帶53之兩端部54可利用縫合之方式固定於左右側面49、51。In addition, the cold storage bag 1 may be provided with shoulder belts 53 whose both ends are attached to the bag body 23 . In this case, for example, as shown in FIGS. 1 and 2 , the shoulder straps 53 may be formed in such a way that between the left and right side surfaces 49 and 51 of the bag body 23 , a strip of woven cloth or synthetic resin (molded product) is provided. , cloth, leather and other thin belt-shaped shoulder straps 53, the two ends 54 of the shoulder strap 53 can be fixed on the left and right sides 49, 51 by sewing.

再者，於該保冷袋1中，該肩帶53具有如下長度，即，當將該保冷袋1放置於地面使肩帶53垂向下方時，長度方向之中央部分會與地面接觸，又，於該肩帶53之中央部分安裝有具有肩帶53之總長之大致1/3之尺寸(長度L)的板狀之肩托55。此處省略更多細節。Furthermore, in the cold storage bag 1, the shoulder straps 53 have a length such that when the cold storage bag 1 is placed on the ground with the shoulder straps 53 vertically downward, the central portion of the length direction will contact the ground, and further, A plate-shaped shoulder rest 55 having a size (length L) of approximately 1/3 of the total length of the shoulder strap 53 is attached to the central portion of the shoulder strap 53 . More details are omitted here.

其次，參照圖2、3，對本發明之一實施形態之可折疊式保冷袋1更詳細地進行說明。如圖2、3所示，本發明之一實施形態之可折疊式保冷袋1構成為，具備：袋本體23，其具有側面部25及底面部24；蓋體27，其安裝於該袋本體23；底面絕熱部26，其設置於該袋本體23；以及側面絕熱部28；且為了增加使用該保冷袋時該側面絕熱部28與該底面絕熱部26之接觸面積，該可折疊式保冷袋具備自該側面絕熱部28延伸之反折部41。此處，圖3所示之反折部41與側面絕熱部28一同形成為大致板狀，藉由將反折部41適當彎折而使其與底面絕熱部26接觸。如此便可於折疊保冷袋1時，使反折部41與側面絕熱部28大致平行，藉此可不使經折疊之保冷袋之厚度不必要地增大。Next, referring to FIGS. 2 and 3 , the foldable cold storage bag 1 according to one embodiment of the present invention will be described in more detail. As shown in FIGS. 2 and 3 , a foldable cold storage bag 1 according to an embodiment of the present invention is configured to include a bag body 23 having a side surface 25 and a bottom surface 24 , and a lid 27 attached to the bag body 23; the bottom surface heat insulating part 26, which is arranged on the bag body 23; The inversion portion 41 extending from the side heat insulating portion 28 is provided. Here, the folded portion 41 shown in FIG. 3 is formed into a substantially plate shape together with the side heat insulating portion 28 , and the folded portion 41 is appropriately bent so as to be brought into contact with the bottom surface heat insulating portion 26 . In this way, when the cold-insulation bag 1 is folded, the folded portion 41 and the side insulating portion 28 can be made substantially parallel, thereby preventing the thickness of the folded cold-insulation bag from being increased unnecessarily.

如此，根據本發明之一實施形態之可折疊式保冷袋，藉由設置反折部，可容易地折疊保冷袋，並且可藉由確實地減少冷氣自各個面之絕熱部間流出，確實地提昇保冷效果。In this way, according to the foldable cold-insulation bag of one embodiment of the present invention, by providing the folded portion, the cold-insulation bag can be easily folded, and the outflow of cold air from between the heat-insulating portions of each surface can be surely reduced, and the lift can be surely lifted. Cooling effect.

此處，可知保冷袋之保冷效果取決於2個要素，其中一個為來自載置保冷袋之地面之熱影響，另一個為冷氣自保冷袋內之洩漏(尤其是冷氣自底部附近之洩漏)，為了降低前者之影響，可較厚地形成底部絕熱部，但由於重量及尺寸之制約而存在限度，關於後者可知，有效地防止冷氣自個別地成形之底面絕熱部與側面絕熱部之間洩漏較為重要，本申請案之發明人發現了其具體對策。再者，側面絕熱部28可藉由在形成1個板狀絕熱部後，將該板狀絕熱部彎折且將其兩端部適當連結、接著而形成。Here, it can be seen that the cooling effect of the cold-insulation bag depends on two factors, one of which is the thermal influence from the ground on which the cold-insulation bag is placed, and the other is the leakage of cold air from the inside of the cold-insulation bag (especially the leakage of cold air from near the bottom), In order to reduce the influence of the former, the bottom heat insulating portion can be formed thicker, but there are limitations due to weight and size constraints. Regarding the latter, it can be seen that it is important to effectively prevent the leakage of cold air from between the individually formed bottom heat insulating portion and the side heat insulating portion. , the inventor of the present application has discovered its specific countermeasures. In addition, the side heat insulating portion 28 can be formed by forming one plate-like heat insulating portion, bending the plate-like heat insulating portion, appropriately connecting both ends thereof, and then forming the plate-like heat insulating portion.

又，如圖3所示，於本發明之一實施形態之可折疊式保冷袋1中，該反折部41以覆蓋該底面絕熱部26之端部34之方式設置。如此，可防止冷氣自底面絕熱部與側面絕熱部之間洩漏，從而可提高保冷效果。Furthermore, as shown in FIG. 3 , in the foldable cold storage bag 1 according to one embodiment of the present invention, the folded portion 41 is provided so as to cover the end portion 34 of the bottom surface heat insulating portion 26 . In this way, cold air can be prevented from leaking from between the bottom surface heat insulating portion and the side surface heat insulating portion, so that the cooling effect can be improved.

於本發明之一實施形態之可折疊式保冷袋1中，該反折部41之長度處於5 mm至170 mm之範圍內。可知，如此可防止保冷袋內之冷氣之洩漏或來自地面之熱影響。本發明人等進行了試驗，結果發現經過一定時間後之殘冰率提昇7%以上。In the foldable cold-insulation bag 1 according to an embodiment of the present invention, the length of the folded portion 41 is in the range of 5 mm to 170 mm. It can be seen that this can prevent the leakage of the cold air in the cooling bag or the thermal influence from the ground. The inventors of the present invention conducted tests and found that the residual ice rate was increased by more than 7% after a certain period of time.

又，藉由將反折部41之長度設為上述範圍，折疊保冷袋1時，可使根據箱之尺寸折疊時之尺寸小型化，藉此可實現折疊之簡易性或減少折疊狀態之保冷袋之厚度。In addition, by setting the length of the folded portion 41 to the above-mentioned range, when the cold storage bag 1 is folded, the size when folded according to the size of the box can be miniaturized, thereby realizing the ease of folding or reducing the number of cold storage bags in the folded state. thickness.

於本發明之一實施形態之可折疊式保冷袋1中，該反折部41構成為形成於該側面絕熱部28之全周。如此，可防止冷氣自底面絕熱部與側面絕熱部之間洩漏，從而可進一步提高保冷效果。In the foldable cold storage bag 1 according to one embodiment of the present invention, the folded portion 41 is configured to be formed on the entire circumference of the side heat insulating portion 28 . In this way, cold air can be prevented from leaking from between the bottom surface heat insulating portion and the side surface heat insulating portion, so that the cooling effect can be further improved.

其次，參照圖4a、4b，對本發明之一實施形態之可折疊式保冷袋1進行說明。如圖4a、4b所示，於本發明之一實施形態之可折疊式保冷袋1中，該反折部41例如於該側面絕熱部28之第1側面絕熱部19和與之相鄰之第2側面絕熱部20及第3側面絕熱部21之交界區域被切缺。如圖4a、4b所示，對於其他側面絕熱部，該反折部41亦同樣地被切缺。如此，可防止反折部重疊，更有效地防止冷氣自底面絕熱部與側面絕熱部之間洩漏，從而可進一步提高保冷效果。Next, referring to Figs. 4a and 4b, the collapsible cold storage bag 1 according to one embodiment of the present invention will be described. As shown in Figs. 4a and 4b, in the foldable cold storage bag 1 according to an embodiment of the present invention, the folded portion 41 is, for example, the first side heat insulating portion 19 of the side heat insulating portion 28 and the first side heat insulating portion 19 adjacent thereto. The boundary region between the second side heat insulating portion 20 and the third side heat insulating portion 21 is cut out. As shown in Figs. 4a and 4b, the folded portion 41 is similarly cut out for the other side heat insulating portions. In this way, it is possible to prevent the folded portions from overlapping, and to more effectively prevent cold air from leaking from between the bottom surface heat insulating portion and the side surface heat insulating portion, thereby further improving the cooling effect.

於本發明之一實施形態之可折疊式保冷袋1中，該反折部41以覆蓋該底面絕熱部26之方式設置。如此，可進一步防止保冷袋內之冷氣之洩漏或來自地面之熱影響。In the foldable cooling bag 1 according to an embodiment of the present invention, the folded portion 41 is provided so as to cover the bottom surface heat insulating portion 26 . In this way, it is possible to further prevent the leakage of the cold air in the cooling bag or the thermal influence from the ground.

於本發明之一實施形態之可折疊式保冷袋中，該反折部41以覆蓋該底面絕熱部26之表面積的5%至100%之範圍內之表面積之方式設置。如此，可防止保冷袋內之冷氣之洩漏或來自地面之熱影響。In the foldable cold-insulation bag according to an embodiment of the present invention, the folded portion 41 is arranged to cover the surface area within the range of 5% to 100% of the surface area of the bottom surface heat insulating portion 26 . In this way, the leakage of the cold air in the cold-insulation bag or the thermal influence from the ground can be prevented.

其次，圖5示出本發明之一實施形態之可折疊式保冷袋1被折疊之狀態。如圖所示，拉開蓋體27及底面部24之各個拉鏈29，進行開封。使蓋體27及底面部24自該狀態交錯地彎曲270度，從而以各表面與相對向之側面之外表面接觸之方式進行重疊。繼而，使側面部49、51呈く字狀地中央凹陷。繼而，利用位於底面部24之內側之附魔鬼氈之帶(未圖示)進行保持，並可藉由預先取出肩帶53，而將保冷袋1掛在肩上。此處，可知，藉由使蓋體27與底面部24交錯地打開，可使其等以與相對向之各側面接觸之方式旋轉，從而使折疊變得更簡易且緊湊。Next, Fig. 5 shows a state in which the foldable cold-insulation bag 1 according to one embodiment of the present invention is folded. As shown in the figure, each zipper 29 of the lid body 27 and the bottom surface part 24 is pulled open, and it is unsealed. From this state, the lid body 27 and the bottom surface portion 24 are bent alternately by 270 degrees so as to overlap each other so that each surface is in contact with the outer surface of the opposite side surface. Next, the side portions 49 and 51 are recessed in the center in a U-shape. Then, the belt (not shown) with devil felt on the inner side of the bottom surface 24 is used for holding, and the cooling bag 1 can be hung on the shoulder by taking out the shoulder belt 53 in advance. Here, by opening the lid body 27 and the bottom face portion 24 alternately, the lid body 27 and the bottom face portion 24 can be rotated so as to be in contact with each of the opposing side surfaces, thereby making the folding easier and more compact.

如此，於折疊保冷袋1時，可使反折部41與側面絕熱部28大致平行，藉此可不使經折疊之保冷袋之厚度不必要地增大。In this way, when the cold-insulation bag 1 is folded, the folded portion 41 can be made substantially parallel to the side insulating portion 28, thereby preventing the thickness of the folded cold-insulation bag from being unnecessarily increased.

如此，根據本發明之一實施形態之可折疊式保冷袋，藉由設置反折部，可容易地折疊保冷袋，並且可藉由確實地減少上述冷氣自各個面之絕熱部間之流出，確實地提昇保冷效果。In this way, according to the foldable cooling bag according to one embodiment of the present invention, by providing the folded portion, the cooling bag can be easily folded, and the outflow of the cold air from between the heat insulating portions on each surface can be reliably reduced. Improve the cooling effect.

參照圖6、7，對本發明之一實施形態之保冷袋之一實施形態進行說明。如圖所示，本發明之一實施形態之保冷袋10具備袋本體23，形成為具有底面及側面之盒狀，將內部作為收納部，且於上部開有收納口，上述袋本體23於外側配置有將PVC/PU/EVA塗佈於尼龍或聚酯織布所得之防水布，內裝PE或苯乙烯等合成樹脂發泡材，並於內側配置有尼龍或聚酯布，具有防水性(或正背相反地使用該防水布面)。如下所述，於袋本體23之內表面之各個面設置收容有絕熱材之絕熱部作為側面絕熱部及底面絕熱部。再者，考慮各種態樣來將絕熱部安裝於袋本體23之各個面，並不限定於特定態樣。6 and 7, one embodiment of the cold storage bag according to one embodiment of the present invention will be described. As shown in the figure, a cold storage bag 10 according to an embodiment of the present invention includes a bag body 23, which is formed into a box shape with a bottom surface and a side surface, uses the interior as a storage portion, and has a storage opening in the upper portion, and the bag body 23 is located on the outside.

In addition, although various aspects are considered and the heat insulating part is attached to each surface of the bag main body 23, it is not limited to a specific aspect.

由與袋本體23相同之材料形成之蓋體27經由以合成樹脂片(例如尼龍或聚酯織布等)所構成之鉸鏈構件(未圖示)連結於收納口之一側(下述背面側側面35)，於將該蓋體27蓋住收納口時(利用蓋體27封閉收納口時)覆蓋袋本體23之上部外周之拉鏈部29沿著該外周，延伸設置於蓋體27之周緣部。此處，於蓋體27之內表面設置收容有絕熱材之絕熱部作為上表面絕熱部。再者，考慮各種態樣來將絕熱部安裝於蓋體27，並不限定於特定態樣。A lid 27 formed of the same material as the bag body 23 is connected to one side of the storage opening (the back side described below) via a hinge member (not shown) made of a synthetic resin sheet (such as nylon or polyester fabric). Side 35), when the cover body 27 covers the storage opening (when the storage opening is closed by the cover body 27), the zipper part 29 covering the outer periphery of the upper part of the bag body 23 extends along the outer periphery and extends from the peripheral edge of the cover body 27 . Here, a heat insulating portion containing a heat insulating material is provided on the inner surface of the lid body 27 as an upper surface heat insulating portion. In addition, various aspects are considered for attaching the heat insulating portion to the cover body 27, and the invention is not limited to a specific aspect.

保冷袋10亦可具備一對之兩端部安裝於該袋本體23之手提式把手33。例如，如圖6、7所示，該手提式把手33安裝於袋本體23之正面側側面31及背面側側面35之上部外周，但並不限於此。又，於圖示之例中，該手提式把手33構成為一對U字形把手37、39。再者，該手提式把手33即兩個U字形把手37、39例如亦可於用手搬運保冷袋10時，中央部分可由縫合有魔鬼氈43、45之環狀之把手合攏抓手47收攏為一體。The cold-insulation bag 10 may also include a pair of portable handles 33 whose both ends are mounted on the bag body 23 . For example, as shown in FIGS. 6 and 7 , the portable handle 33 is attached to the upper outer periphery of the front side side 31 and the back side side 35 of the bag body 23 , but is not limited thereto. In addition, in the example shown in the figure, the portable handle 33 is configured as a pair of U-shaped handles 37 and 39 . Furthermore, the portable handle 33, that is, the two U-shaped handles 37, 39, can also be used to carry the cold-insulation bag 10 by hand. one.

又，保冷袋10亦可具備兩端部安裝於該袋本體23之肩帶(shoulder belt)53。於此情形時，例如，如圖6、7所示，該肩帶53可以如下方式形成，即，於袋本體23之左右側面49、51間，架設一條由織布或合成樹脂(成形品)、布帛、皮革等構成之薄帶狀之肩帶53，該肩帶53之兩端部54可利用縫合之方式固定於左右側面49、51。In addition, the cold storage bag 10 may be provided with shoulder belts 53 attached to the bag body 23 at both ends. In this case, for example, as shown in FIGS. 6 and 7 , the shoulder straps 53 may be formed as follows, that is, between the left and right side surfaces 49 and 51 of the bag body 23 , a strip of woven cloth or synthetic resin (molded product) is provided. , cloth, leather and other thin belt-shaped shoulder straps 53, the two ends 54 of the shoulder strap 53 can be fixed on the left and right sides 49, 51 by sewing.

再者，於保冷袋10中，該肩帶53具有如下長度，即，當將保冷袋10放置於地面使肩帶53垂向下方時，長度方向之中央部分會與地面接觸，又，於該肩帶53之中央部分安裝有具有肩帶53之總長之大致1/3之尺寸(長度L)的板狀之肩托55。此處省略更多細節。Furthermore, in the cold storage bag 10, the shoulder straps 53 have a length such that when the cold storage bag 10 is placed on the ground and the shoulder straps 53 are vertically downward, the central portion of the length direction will contact the ground, and in this A plate-shaped shoulder rest 55 having a size (length L) of approximately 1/3 of the total length of the shoulder strap 53 is attached to the central portion of the shoulder strap 53 . More details are omitted here.

其次，參照圖8、9、11，對本發明之一實施形態之保冷袋10更詳細地進行說明。如圖8、9、11所示，本發明之一實施形態之保冷袋10構成為，具備：袋本體23，其具有底面部24及側面部25；蓋體27，其安裝於該袋本體23；底面絕熱部26，其設置於該袋本體23；以及側面絕熱部28；且為了增加使用該保冷袋時該側面絕熱部28與該底面絕熱部26之接觸面積，該保冷袋10具備自該側面絕熱部28於垂直方向上延伸之延伸部30或形成於該底面絕熱部26之階部32之至少任一者。此處，於圖8之例中，延伸部30與側面絕熱部28一同形成為大致板狀，藉由將延伸部30適當彎折而使其與底面絕熱部26接觸。另一方面，於圖11之例中，延伸部30與側面絕熱部28一同藉由模具形成。Next, referring to FIGS. 8 , 9 and 11 , the cold storage bag 10 according to one embodiment of the present invention will be described in more detail. As shown in FIGS. 8 , 9 and 11 , the cold storage bag 10 according to an embodiment of the present invention is configured to include a bag body 23 having a bottom surface portion 24 and a side surface portion 25 , and a lid body 27 attached to the bag body 23 . The bottom surface heat insulation portion 26, which is provided on the bag body 23; and the side heat insulation portion 28; At least one of the extension portion 30 extending in the vertical direction of the side heat insulating portion 28 or the step portion 32 formed on the bottom heat insulating portion 26 . Here, in the example of FIG. 8 , the extension portion 30 is formed into a substantially plate shape together with the side heat insulating portion 28 , and the extension portion 30 is appropriately bent to make contact with the bottom surface heat insulating portion 26 . On the other hand, in the example of FIG. 11, the extension part 30 is formed by the mold together with the side heat insulating part 28.

根據本發明之一實施形態之保冷袋，無需一體地成形底面絕熱部與側面絕熱部，故而不僅可更簡易且低成本地進行各個面之絕熱部之成形，而且可藉由確實地減少冷氣自各個面之絕熱部間流出，提昇保冷效果。According to the cold storage bag of one embodiment of the present invention, it is not necessary to integrally form the bottom heat insulating portion and the side heat insulating portion, so that not only can the heat insulating portion of each surface be formed more easily and at low cost, but also the cold air can be reliably reduced by The heat-insulating part of each surface flows out to improve the cooling effect.

此處，可知保冷袋之保冷效果取決於2個要素，其中一個為來自載置保冷袋之地面之熱影響，另一個為冷氣自保冷袋內之洩漏(尤其是冷氣自底部附近之洩漏)，為了降低前者之影響，可較厚地形成底部絕熱部，但由於重量及尺寸之制約而存在限度，關於後者可知，有效地防止冷氣自個別地成形之底面絕熱部與側面絕熱部之間洩漏較為重要，本申請案之發明人發現了其具體對策。再者，側面絕熱部28可藉由在形成1個板狀絕熱部後，將該板狀絕熱部彎折且將其兩端部適當連結、接著而形成。Here, it can be seen that the cooling effect of the cold-insulation bag depends on two factors, one of which is the thermal influence from the ground on which the cold-insulation bag is placed, and the other is the leakage of cold air from the inside of the cold-insulation bag (especially the leakage of cold air from near the bottom), In order to reduce the influence of the former, the bottom heat insulating portion can be formed thicker, but there are limitations due to weight and size constraints.
